Modular Rigging with Python.

Anyone else having a problem in the 9th lesson
on line 59 with the implementation of the button?
I keep getting an indent error that I can't seem to fix.
Done it 4 times now....same result.
I'm in 2010, so I don't get why it's not working.
My code looks identical to Steve's.
Do I need to install Python on my system maybe? ....and if so, what version.
Or has anyone else gotten past this?

If you want to give it a try I recommend taking a look at PyCharm. It is an IDE for python from JetBrains. Last I tried it took a bit to get it hooked up to Maya's python interpreter. However once it was hooked up it made me far more productive. It will automatically detect syntax errors, has code completion so you don't have to really worry about spelling mistakes and various other things, things that I found annoying when trying to work out of a notepad like text editor like notepad++ or Maya's script editor.

On a side note I have been wanting to start the Modular Rigging course. I picked it up on the sale 3DBuzz had awhile back but I haven't had time to start.
